New words

The Merriam-Webster dictionary has added new entries. Words like frenemy — a friend who's really an enemy — are not exactly new. The point is they're now widely used. Other new entries include: Webisode, flash mob and staycation.

"There are words such as locavore (one who eats foods grown locally), frenemy (someone who acts like a friend but is really an enemy), waterboarding (an interrogation technique use to induce the sensation of drowning), vlogs (a blog that contains video material) and webisode (a TV show that can be viewed at a Web site).

There's also flash mob (a group of people summoned electronically to a designated spot at a specified time to perform an indicated action before dispersing) and green-collar (involving actions for protecting the natural environment)."
